Spinilophus armatus Müller & Henle, 1841

New Ireland stingaree, Black-spotted stingaree



Taxonomy & Nomenclature



Conservation Status

Only known from the juvenile holotype collected in the 1820's (1822-1825).

IUCN RedList assessment: Data Deficient (2006)


There have been no records of the species since the holotype was collected. It is extremely rare and possibly extinct, although fishing pressure seems almost non-existent in the reported area of collection. It is perhaps better treated as a naturally rare species with an extremely limited natural distribution.



New Ireland, Bismark Archipelago, Papua New Guinea





Holotype only.
